Time Evolution of Open Quantum Systems Toward Evolving Bio-inspired Energy Transfer

Open quantum system dynamics study time evolution of a quantum system that interacts with an environment, however, complexity of both system and environment makes exact calculations often impractical to obtain. We aim to find a reliable method relevant for studying energy transfer in long-ordered open quantum systems, polymer chlorosome nanocomposites (PCN). PCNs, artificial light harvesting systems, are an ideal candidate for studying energy transfer in open quantum system because PCNs are modifiable and exhibit efficient energy transfer over long distances. In this work, the population dynamics of four PCN systems have been simulated using the Lindbladian master equations. Each system consists of one of four types of chromophore molecule, Bchl. C,D,E,F, and are arranged in a J-like aggregate structure. Our results show how different molecules affect the energy transfer within the PCNs, and how PCN systems can be used to increase understanding of the energy transfer process.
